There's a certain list of things we routinely clean, but your debit and credit cards probably aren't on that list — but they should be! It's easy and can greatly extend the life of your card.

You might be wondering why you should bother, but if you've gone cardless for a few days while waiting on a replacement, the extra step of cleaning your cards can go a long way toward preventing such a hiccup.
All you need is an eraser and a damp towel. Wipe the card clean with the towel to remove any grimey build up deposited onto your card from your wallets or card reader machines. It's not something that gets extra dirty, but the small particles when compacted with continuous swiping/use can rub off the magnetic strip holding your card's information.
Next take the eraser and gently erase/rub the magnetic strip on the back. It will remove any gunk that's built up over time. This trick also works with old-school cartridge-based gaming systems, just in case you really have the urge to play some NES Duck Hunt.
